I appreciate that but I'm hardly an expert. It's just that I was there. I raced a few time trials circa the early 80s. Everyone was still riding road bikes. Also I was working in bike shops the whole decade. Fun thread regardless.
There's usually a big messy overlapping transitional period when new cycling tech is introduced. This is the case with time trial bikes for sure. Also, I've heard from friends descriptions of experimental track bikes built for pursuit racing in the late 70s. While it might be debatable as to whether that's a TT bike, it falls within your larger range. (sorry no pics) And let's not forget the very first special TT bike, the Mochet Velocar. This was raced very successfully in 1934 and earlier IIRC, before the concept was eventually banned.
